srnorrrca'non forming'part of'Letters intent No. 780,380, dates- Janu ry 17, 1905. i Application filed September 24,1902. .Serial No. 124,710..' r a i in the county ofArmstrong and State of Penn:

sylvania, have invented new anduseful Im- 'provements in Type writer s, o f'which the following is a specification.

My invention relates to improvements in type-writer's, and pertains particularly to that class of machines in which the writing is visible and'in which the type-bars are pivot-ed in the pertains to means for automatically locking ar of a vertical circle and extend outward and normally lie in a horizontal or approximately' horizontal position.

One feature of my present invention relates to an arrangement of key-levers which 'move in a vertical plane and the connection between the key-levers and type-barswh ereby anexs 'ceedingly easy and quickacting key-lever touch is provided. I I

Anotherfeature of my present invention the vertically-shifting type-bar basket or action against movement when a key-lever. is depressed, thus enabling me to provide a light shift and at the same time absolutely prevent any possible impe'rfection of alinement no matter how heavy, uneven, or jerkythetoueh "of the operator. v

In the accompanying drawings, Figure 1 is a longitudinal central vertical section of amachine embodying my invention. Fig. 2 is a detached perspective view of the type-bar bas hot with only a portion of the'type bars shown in'position therein to more clearly disclose the specific construction and relative arrangement of the type-bars and key-lever connections. Fig. 3 is a side elevation of my improvedtypewriter, the frame of the machine being broken away to disclosethe 'aritomatic'type-bafibds-' 'ket lock. Fig. .4is an enlarged detached-perspective view of the automatic type-bar-basket lock. Fig. 5 is a top plan view on line 3 3 of Fig. 1, the type-bar basket being removed to disclose the universal feed-bar and its connection with [the automatic type-bar-basket lock. 6 is anenlarged detached perspective view of a modified form of thelock' for the type-bar basket.

In a machine of. the character herein shown there is provided 'an essentially horizontal frame 1,,having atone end the vertically-aw. ranged standards 2, upon which issupported' asuitable carriage, and situated within the said-horizontal frame'1 below the carriage is a vertically-shifting type-bar basket .3), in

which are arranged in the arc of a vertical circle-the type bars, and below thetype-bars are arranged the key-levers. Thekey-levers,

however, in the construction here sho'wnare not arranged in the arc of a vertical circle, as are the type-bars, and hence the key-levers have a true vertical movement.

" The combined type-bar and key-lever bas-.

the horizontal frame 1, and these trunnions are removably held within the said grooves through the medium of any'suitable locking device'such, for instance, as a hook or lug 7, here shown. I I

Referring now to the construction and arrangement of; the type-bar basket. thejtypebars, and the key-levers, it will be noticed.

that one end of the type-bar basket consists ofia block 9, having grooves in its upper and lower sides, and that the type bar divisionplates 11 are located in these grooves. The type-bars 1 2 are situated between these divis sion-plateS and are pivotally supported by the said division-plates 11 at their inner ends through themedium of a suitable rod -14. The outer-and-free endsof the type-bars carry type-bar blocks 15, which contain the caps and small letters. as is well understood by those skilled in the art.

Depending downward at a point intermedi-' ate the end of the type-bar basket is a vertiby the verticallyerranged slots20. formed in a downwardly projecting plate 21, which is situated at the opposite or outer end of the same time provide. an easy and quick-acting typebar basket to that at which the type bars are pivoted. In a type-writer of the character here shown it is necessary that the type-bars be arranged inthe arc of a vertical circle and radially in respect thereto,- audit is one object of my present inventionto provide means whereby improved connections-are arranged between thekey-levers and typebars which will permit the key-levers tohave a true vertical movement irrespective'of the radial movement of the type-bars and at'the key-lever touch.

My improved connection consists in pivoting a plurality of levers 22 at the point 23, which is intermediate the ends of the said levers, the inner ends of theflevers being suit-' ably operatively connected with the inner pivoted ends of the type-bars. As here shown, the connections between the levers 22 and the type-bars consist of sockets 24, carried at the inner ends of the levers 22, and the coasting members 25', carried by the pivoted ends of the type-bars These levers 22 are arranged in the arc of a verticalcircle. {It will benoticed that the pivots ofth e type-bars and the intermediate levers 2'2 lie in the surface of a cylinder the axis of which passes. through the printing-point.- The opposite ends of the levers 22 are connected with the key-levers through the medium of wire links 26, and

these wire links are arranged alternately out of line, as shown, for the purpose of preventing any interference of their curved ends at the adjacent sides of key-levers and intermediate levers 22. 4

A connection between'the key-levers and the type-bars such as here shown enables me to provide a simple yet very effective arwithout provision to prevent it a very heavy or. jerky touch upon the key-levers is likely to cause a vibration of the inner end of the of the inner end of the type-bar basket, 1 pro- 6o gages and locks the inner vertically-shifting type-bar basket, and thus affect the alinement.

In order to enable a light shift and at the same I time to prevent any-possible imperfection in the'ahnement because of a vertical vibration vide an automatic lock which automatically enend of the type-bar basket when a key-lever is depressed, thus making it impossible to affeet the alinement no matter how imperfect,

how heavy, or how jerky the touch of the op:

erator may be. Generically speaking, the lock consists of a'member which is coptrolled by either a key-lever or ashift-lever, whereby the basket is locked in its downward position when the key-lever is depressed and is released when a shift-key is depressed for shifting the inner end of the type-bar basket. The specific arrangement here shown is under the control of the key-levers, though, as just stated, without affecting the scope of my invention the lock may be under the control of the shift-key. In. the form here shown a vertically-arranged latch 28 is provided, and the said latch is pivotally supported by the frame of. the machine at the point 29. This latch 28 is located adjacent the inner vertically-pivoted end of the type-bar basket, and its shouldered end 30 is adapted to engage a. pin or shoulder 31, carried by the movable portion of the type-bar basket. The universal feed-frame 32 has its-free end 33 located ated thereby in the usual manner. The opposite and pivoted end of the universal frame 32 is provided with'a member 34, which interlocks with the latch 28 for the purpose of moving the latch over the shoulder or pin Ell of the type-bar basket when akcy-lever is depressed. As soon as the key-lever is depressed the latch immediately engages the shoulder or pin 31 of the type-bar basket and before the key-lever reaches the limit of its downward movement. and'hence absolutely locks the type-bar basket against any vertical vibration under a jerky, heavy, or imperfeet touch, as will be readily understood. Each time a key-lever is depressed the latch is brought over the pin or shoulder 31 of the type-bar basket and immediately locks the same against any vertical vibration whatever, and thus absolutely preventing any imperfeet alinemeht on account of any vibration of the free or vertically-shifting end of the typebar basket. VVhile I have here shown and described the lock under the control of the already stated) that the shift-key may be connected with the latch and in which instance the shoulder or projection upon the movable portion of the type-bar basket.- W hen, how- .ever, the shift-key is depressed, the latch will be moved out of engagement with the shoulder or projection and permit the basket to be shifted vertically. Therefore my generic invention consists in providing-a lock for the type-bar basket which is controlled either by atype-bar key-lever or a shiftdiey lever, and

tended to include either a type-bar key-lever or a shift-key lever unless prefixed by a limitation, such as type-bar or shift.

' In Fig. 6 1 show a form oflock for the type-bar basket which is controlled by the key-levers, it will be readily understood (as' the latch will be normally in engagement with under the key-levers and adapted to be actuthe termkey-lever, as hereinafter used in claims relating to this locking device is ,in

through the printing-point, said intermediate shift-lever 32'. IA rod or extension 33' i- 7 tends from the saidlever 32 and engages the notch 30 of the latch 28. In this instance (the inner end of the lever 32' is located sufficiently below the type-bar-basket shoe 35 to permit suliicient movement thereof to'opcrate the latch before engaging the shoe, and the latch 28 is in this'moditied form in con- .stant engagement with the pin 31 of the typebar basket.\ U 7 Having thus described my invention, what I claim,'and desire to secure by Letters Patcut, is v l.
